Dear @wolfie62 : Now I own that ADC in stock condition. I posted a thread of the ADC 26/27 original status where I made tests comparisons against top today LOMC cartridges and overall in my room/system me and the owners of the today LOMC cartridges been in agreement that that Pritchard design is just superb and could outperform any other cartridge.
I know that you prefer the 10E MKIV and is ok. I have the 26 with 3-4 replacement stylus and now that you brougth here ADC name I will send to an update with boron cantilever and maybe Shibata stylus shape or VDH and yes with the length cantilever of same dimension than the original aluminum one.
